Hi!I've been trying to figure out what is the format of the signature blob.It's not CMS nor binary plist. Googling yielded no results.I extracted the blob using jtool (of course), maybe I need to delete some bytes in order to get the correct format? There are entitlements (bplist) and certificates (DER I suppose), it has to have some structure.

I couldn't find a way to buy an electronic copy of V III and it would take the shipment a month to reach me anyway, so could you please share some details on what Type is? I assume the symbols after @ are an offset and Code Directory is __TEXT + __DATA (or is it?).Should I supply any additional information regarding the unhandled opcode?

shipping is linear, so I don't know how much that would save. And there are no eBooks due to rampant piracy of my other works. But here's a sample of what you're missing which answers your questions as well. Btw, Security.framework is OpenSource, and libsecurity_codesigning is also helpful in figuring this stuff out.
